Rabbit 2000 - LD (Iy+D),Hl

64 Rabbit 2000/3000 Microprocessor
Description
• LD (IY+d),HL: Loads the data in L into the memory location whose address is the sum of
the data in IY and a displacement value d. Then, loads the data in H into the memory location
whose address is the sum of the data in IY and a displacement value d plus 1.
• LD (IY+d),n: Loads the 8-bit constant n into the memory location whose address is the
sum of the data in IY and a displacement value d.
• LD (IY+d),r: Loads the data in r (any of the registers A, B, C, D, E, H, or L) into the mem-
ory location whose address is the sum of the data in IY plus a displacement value d.
